The advertized balance current is proportional to the voltage difference.. Si If you get a 2A balance active BMS it will balance at 2A ONLY if the voltage diff of the cell being discharged is very high. When voltage difference is below 100mV for exemple the balance current in not 2A but will be maybe 10 times less
So i can charge my EVE cells with 0.5C without a problem but once the active balancer moves 2A then the batteries will overheat? Please clarify by masurements and thermal camera.
my concerns all this year while balancer never stops.... after 6 monthd my first gen jk has perfectly kept my pack of 16... but when go to 280+ amps cellls ,I will use the inverter new one. . then i m going 20/75 % so i m going to balance once per 3 months average and not always ON .,because 75% is close to 3.4v and passive balancing will eventualy take place unless a cell is ruined . when paralel old vs new in same inverter system at least one has Amp share limiter so no need both to have such feature
When you buy best grade cells, the need for an active balancer will be more or less zero. IMO active balancers are just overhyped. My oldest packs with passive balance BMSs and no monitoring are doing a great job. My newest pack with a Pace Inverter BMS and passive balancing is doing as well a great job, albeit I first needed to set correct parameters as the biggest problem with any BMS is that factory settings are mostly useless when it comes to balancing...
with an active balancer, you save fewer cycles that could go to waste and have more capacity to use too, A passive balancer is an old system, it wastes energy that can be useful to you
On very new cells, yes, an active balancer seems, or is a bit unnessesary. But for sure, that over time, the balancer needs to work more as the cells degrade. However, a bms remains nessesary, it does more than just balance the cells. It guards against undervoltage, overvoltage, shorts, temprature, and what not. If the bms also has an active balancer, then why not ? Using lifepo cells without a bms is risky and just stupid.
I have 1 battery (20KWH) with 60mA passive balancing. And 1 battery (40KWH) with 4A active balancing. The passive balance creates much more heat, despite being 30 times smaller balance capacity My real world advice = always go for an active balancer
makes no sense passive balancer generates way more heat than an active balancer the point is that an active balancer costs more to make as it requires more hardware, so lady don't give the wrong information out here
I have 9 JK BMS on EVE MB31 cells. I set the requested charge voltage to 3.5v per cell, the balance start voltage at 3.45v per cell, and the requested float voltage at 3.4v per cell. The JK gives you the internal temperatures of the board and I can say from experience the BMS gets WAYY hotter when you’re pulling 0.5C through it than anything I’ve seen from the balancer. This video is false.

Hallo den Speicher würde ich gern auf meinen UA-cam vorstellen 👍
over heating with 2A? Realy? 2A X 3-4.2 Volt per Cell it is only 6-8.4Watts
those amps should go from one cell to the other so this should not generate heat
